I too will be traveling for 4 months. NEW Visa rules. We will get 60 days stamp upon arrival. Then I’ll apply for a 30 day extension. Then I’ll travel out to Cambodia or Vietnam for a short visit and return to Thailand and we will be give a new 60 day stamp.
I think the main distinction is that in an urban setting, apartments/condos can’t allow gas cookers in units due to fire risks. The lack of an oven is that most of their cuisine do not require it plus it’s expensive. I’ve found that cooking at home is more expensive especially for 1. Now I do generally cook breakfast and lunch. And the lack of washing machines is all due to costs. Rental units get a lot of abuse.
